I saw this, and a 30 second glance revealed that it is hugely not worth the money. It's far too expensive. I would have to be around a 150% bonus before I would be interested. Especially in this climate of dynamic pricing for awards these days.
Unfortunately, there must be some clowns around with no sense of the value of money, who make use of this offer. Otherwise, they would never make the offer, or perhaps make a 100% bonus. Even then, I would only use if for topping up the account to achieve a meaningful award. Now, meaningful awards - what were they?
